Claims

[Scope of utility model registration request]

A safety release command circuit that outputs a safety release command signal during use, a first logic circuit that inputs the command signal of this safety release command circuit, and a current amplification circuit that current amplifies the signal of this first logic circuit. , a solenoid-type safety release mechanism that activates a solenoid and releases the safety in response to a command signal from the current amplification circuit and the safety release command circuit, and a second logic circuit that confirms that the solenoid-type safety release mechanism has been activated; an ignition command circuit that outputs an ignition command signal based on the output signal of the second logic circuit; and a third circuit that outputs an output signal based on the ignition signal from the ignition command circuit and the output signal from the second logic circuit. An ignition device comprising: a logic circuit; and an ignition circuit operated by an output signal of the third logic circuit.
